Used primarily in the synthesis of fluorescent dyes and bioimaging agents due to its strong electron-withdrawing properties and ability to enhance photostability. Its rigid aromatic structure makes it valuable in developing sensors for biological molecules and environmental analytes. Also employed in materials science for organic semiconductors and optoelectronic devices, where it contributes to improved charge transport and light emission efficiency. Commonly found in research settings for labeling biomolecules and in the development of fluorescent probes for cellular imaging.
